Prefab Building
with TWS roofing system
Comfort, Durability, and Energy Efficiency for demountable building roofs and industrial marquees
The Thermo Wind Safe (TWS) system is a tarpaulin system composed of a double pressurized membrane, providing the best insulation, comfort, and stability in the entire market for removable structure covers.
The system consists of two layers of PVC fabric with a UV filter, separated by a low-pressure air chamber. This pressure remains stable thanks to a low-energy turbine, which only activates when the pressure drops—something that happens less than five times a day.
Requirements for your prefabricated building with TWS
- 1 device per 10002.
- 200 Volts of power.
- 320 Watts of power supply.
Possible choices for your prefabricated building with TWS
- Translucent fabric: to allow light passage and reduce electrical consumption.
- Opaque fabric: to create spaces completely protected from sunlight.
Benefits of the TWS system for a prefabricated building


Roofs with the TWS system help to create quieter, calmer, safer, and healthier spaces due to their high sealing capacity.
Stability and Rigidity
The air cushion dampens the typical movements of the canvas in the face of wind, thereby avoiding flapping and unwanted noise, while enhancing its stability. Its rigid finish design prevents the accumulation of snow and water.
In addition, the pressurized roof exerts tension on the structure, stiffening it and keeping it steady during strong winds, thus protecting its interior from any perception of movement and improving acoustics.
Insulation
The air cushion in the TWS system acts as a natural insulator against noise and temperature.
The insulation it provides is approximately 4 times greater than that of a single canvas. This system can achieve a coefficient of 1.5K (very similar to that of a sandwich panel with sheet metal and polyurethane foam), compared to 6K for a single canvas.
Waterproofing and Comfort
The thermal barrier created by the TWS system prevents water condensation and the sensation of humidity inside demountable buildings and tents, providing comfortable working spaces that enhance users' health.
Moreover, the TWS system with translucent PVC membranes allows diffuse lighting without shadows, leading to significant energy savings and creating a sense of healthy and pleasant living space.
